CONCLUSION
INTRODUCTION TO WIRELESS COMMUNICATION
Our ultimate goal is to communicate with any type of information with anyone, at anytime, from anywhere. This is possible with the aid of WIRELESS TECHNOLOGY
TYPES OF WIRELESS COMMUNICATION NETWORKS
CELLULAR NETWORK
Evolved from mobile telephone as voice conversation and communication tools for private and business uses
WIRELESS LOCAL AREA NETWORK
Emerged from computer network. It helps business user to expand their service areas by using LAN (faster data transport)
MULTIPLE ACCESS APPROACHES AND NETWORKS IN MULTINETWORK
WIRELESS APPLICATIONS AND SERVICES
WIRELESS APPLICATION
Wireless applications are those which use free space as the transmission medium and do not involve cabling like fibre or copper
WIRELESS APPLICATIONS AND SERVICES (CONT’D)
WIRELESS SERVICES

EVOLUTION FROM 1G TO 5G SYSTEM
1G WIRELESS SYSTEM
Developed in 1980s and completed in early 1990’s
1G was old analog system and supported the 1st generation of analog cell phones speed up to 2.4kbps
Advance mobile phone system (AMPS) was first launched by the US and is a 1G mobile system
Allows users to make voice calls in 1 country
2G WIRELESS SYSTEM
Fielded in the late 1980s and finished in the late 1990s
Planned for voice transmission with digital signal and the speeds up to 64kbps
2G was the digital handsets that we are used today, with 2.5G representing handsets with data capabilities over GPRS
3G WIRELESS SYSTEM
Developed in the late 1990s until present day
Japan is the first country having introduced 3G nationally, and in Japan the transition to 3G is being largely completed during 2005/2006
3G WIRELESS SYSTEM (CONT’D)
Services include:
Global roaming
Superior voice quality and video conference
Data always add–on services (e-mail, personal organizer, etc.)
Information for web surfing, music, news, corporate intranet, transportation service etc.
Purchasing – on-line shopping / banking, ticketing, gambling, games, etc.
3G WIRELESS SYSTEM (CONT’D)
Transmission speeds from 125kbps to 2Mbps
In 2005, 3G is ready to live up to its performance in computer networking (WCDMA, WLAN and Bluetooth) and mobile devices area (cell phone and GPS)
3G: Applications, Services and Market
According to Nokia, 3G applications can be divided into:
Wireless Advertising
Mobile Information
Business Solutions
Mobile Transactions
Mobile Entertainment
Person-to-Person Communications
Bearer Entrance and Periodics
3G: Applications, Services and Market
Difference between regular TDMA and W-CDMA
Difference between regular CDMA and W-CDMA
ISSUES ON 3G WIRELESS SYSTEM
High input fees for the 3G service licenses
Great differences in the licensing terms
Current high debt of many telecommunication companies, making it more of a challenge to build the necessary infrastructure for 3G
Health aspects of the effects of electromagnetic waves
Expense and bulk of 3G phones
Lack of 2G mobile user buy-in for 3G wireless service
Lack of coverage because it is still new service
High prices of 3G mobile services in some countries
4G WIRELESS SYSTEM
4G is a research item for next-generation wide-area cellular radio, where you have 1G, 2G, 3G and then 4G [and 5G]
4G is a conceptual framework and a discussion point to address future needs of a high speed wireless network
It offer both cellular and broadband multimedia services everywhere
Expected to emerged around 2010 - 2015
4G WIRELESS SYSTEM (CONT’D)
4G should be able to provided very smooth global roaming ubiquitously with lower cost
Theoretically, 4G is set to deliver 100mbps to a roaming mobile device globally, and up to 1Gbps to a stationary device. With this in mind, it allows for video conferencing, streaming picture perfect video (i.e. tele-medicine, tele-geo processing application etc.)
4G will bring almost perfect real world wireless or called “WWWW: World Wide Wireless Web
GLOBAL 4G WIRELESS SYSTEM
5G WIRELESS SYSTEM
5G is a completed wireless communication with almost no limitation; somehow people called it REAL wireless world
5G wireless system is only theory and not real
EVOLUTION OF CELLULAR SYSTEM
EVOLUTION OF MOBILE RADIO GENERATION
* COMPARISON BETWEEN 3G, 4G AND 5G
CONCLUSION
Wireless systems becoming an important infrastructure in our society. A virtual global system is a good solution that can efficiently connect many dedicated wireless systems including 2G to 4G cellular systems, wireless LAN, broadcasting systems, etc.
